Patent CA-2424767-A1 (CA)
Title: Improved heat exchanger with floating head
Inventor: WANNI AMAR S
IPC: F28F9/02
Filed: 2003-04-04
Abstract: A heat exchanger in which dead zones and areas of stagnation are significantly minimized or eliminated. The heat exchanger includes at least one floating tubesheet which is movable in a longitudinal direction in response to tube expansion and contraction relative to the heat exchanger shell. The shell is joined to the ends by conical members which preferably join onto the shell at a distance along its length to provide shell extensions which promote better flow patterns in the regions of the tube ends. Tube erosion may be addressed by providing a sacrificial portion of tube length extending beyond the tube sheets so as to make repair and replacement of the eroded portion of tubes significantly cheaper, easier and with minimal process interruption. Because axial or longitudinal flow is employed with respect to the shell-side fluid, tube vibration problems are generally eliminated and fouling is minimized through the use of high fluid velocities. Multiple heat exchangers may be combined in a modular fashion by placing individual exchangers either in series, in parallel or both in order to satisfy various process requirements.

Patent CA-2431411-A1 (CA)
Inventor: TROOST HENRY E IV
IPC: F23N5/20
Filed: 2001-12-04
Abstract: Improved lockout control in oil primary controllers for oil heating systems which allows a reasonable number of user resets and ignition retries in the event of lockout while minimizing the unwanted accumulation of oil in the combustion chamber of the heating system. When the oil primary goes into lockout mode due to failure of combustion to take place, the oil primary is placed in a restricted mode of operation in which a limited number of reset activations and combustion retries may be attempted. If they are unsuccessful, a waiting time interval is then imposed between further successive attempts.  The lockout or trial for ignition time may also be reduced for subsequent attempts, to minimize flooding. Normal operation is returned once a successful combustion cycle has been achieved.

Abstract: A rodenticide which is non-toxic to humans, domestic animals and livestock comprises a water-retentive material as the active ingredient and a rodent attractant. Preferably the water-retentive material is cellulosic material. In certain embodiments the water-retentive material comprises alpha-cellulose. In one preferred embodiment the cellulosic material comprises purified cellulos e derived from the core of the cob of the DK 446 maize hybrid or from the core  of the cob of an agonist of the DK 446 hybrid. It is considered that the unique selective toxicity of such rodenticides arises from the interference with water transport through the gut wall, particularly in the caecum (where  cellulose is digested in rats) The caecum is vestigial in humans, who are no t therefore affected by such materials. A laboratory method of screening candidate water-retentive materials for rodenticidal activity in the field i s disclosed, involving examination of the gut (for compaction and bloating) an d the caecum (for impaction).
